Treatment of Rising Damp
As a first step, London Damp Company’s specialists are careful to ensure that your damp problem is correctly diagnosed. Because the treatments can differ so much—and because damp is a complex issue–it is vital to differentiate between rising damp and penetrative damp. Treating rising damp is not a job for even the most competent DIY enthusiast, as it requires expert knowledge backed by experience in the field.
After an initial damp and timber survey, we are likely to recommend that your home’s damp proof course be augmented with any of the following treatments:
Chemical Damp Course Injection
This is the most commonly used method of treating rising damp. A water-repellent, pore-blocking material is pumped into the section of wall affected by the failure of the original damp proof course. Damp course injection can be a highly effective remedy for rising damp, but the success of treatment depends on the knowledge and skill of the person applying it and on the formulation of the products used.
At London Damp Company, our knowledgeable and highly trained specialists use Dryzone Damp Proofing Cream. The Dryzone system is cleaner and faster to install than other chemical damp course injections, and is virtually odour-free. We prefer this system because it minimises the disruption to your household and outperforms its competitors in terms of effectiveness.
Flooring Membrane or Liquid Damp Proof Membrane
Where your floors are affected by rising damp, we will either lay a flexible polymer flooring membrane over the damp area or apply a liquid floor coating. We favour the Oldroyd Xs flooring membrane, an especially strong polypropylene sheet which can even be used with underfloor heating systems. An excellent alternative is the ECS Epoxy floor coating manufactured by Safeguard: this is applied to your floor by brush or roller, and once dry gives a flexible, water- and bacteria-resistant coating which keeps the damp locked firmly below.
Wherever your walls have been affected by damp, the final step in the curative process is plastering. Because moisture-attracting salts remain in the brickwork and masonry even after your damp problem has been treated, these need to be separated from the surface of the wall where you will later redecorate. London Damp Company’s specialist plasterers are able to treat your wall with salt-retarding render before finishing the job with waterproof or refurbishment plaster.
Rising damp is a serious, complex problem, and its diagnosis and treatment need to be undertaken by experts.
